Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a connecting tool used for connecting corrugated plates that are often used as roofing materials, exterior wall materials, etc.

[Conventional technology]

Conventionally, when connecting corrugated plates made of synthetic resin such as polyvinyl chloride resin or polycarbonate resin, as shown in FIG. 1a to 2-3
They were overlapped to the extent of a mountain (approximately 80mm in overlap width). When the corrugated plates 1 are used as roofing materials, as shown in Fig. 10, the overlapping portions 4 of the peaks of the corrugated plates 1, 1 are attached to a plurality of purlins 2 provided at predetermined intervals with hook bolts. It was attached with a stopper 5 such as.

[Problem that the invention attempts to solve]

However, in the conventional case, the following problems have been pointed out.

When the corrugated board 1 is used as a roofing material, the edge 1a of the corrugated board 1 near the overlapping part H between the purlin materials 2, 2 supporting the corrugated boards 1, 1 as shown in FIG. There was a tendency to produce wavy waves. For this reason, there were many cases in which the connection points were opened and the airtightness was impaired, or the watertightness was impaired and dirt accumulated in the overlapping portion H. In order to avoid this, it is effective to narrow the mutual distance A between the purlin materials 2 and 2 shown in FIG.
Not only is this necessary, but the purlin material 2 greatly impairs lighting performance.

Over time, the overlapping portion H of the two corrugated plates 1 and 1 tends to become dirty with rainwater debris that has entered the gap, impairing the lighting, or making the dirt stand out and spoiling the aesthetics. It was hot. This tendency was remarkable when the transparent corrugated plate 1 was used.

Since differences in the number and dimensions of the overlapping portion H occur due to individual differences among workers, it is difficult to standardize the construction of the corrugated board 1.

An extra corrugated plate 1 is required by the width of the overlapping portion H compared to the width of the corrugated plate 1 at the construction site. In particular, when a standardized corrugated plate 1 having a constant width is used, the larger the width of the construction site, the greater the number of connection points, which lowers the material yield and increases costs.

This invention solves these problems. It is possible to connect corrugated plates to maintain the necessary airtightness and watertightness without overlapping them, and the connection points are less likely to get dirty, making it possible to standardize construction. Moreover, it is an object of the present invention to provide a connecting tool that improves the yield of corrugated plates.

[Means for solving problems]

In order to achieve the above purpose, the connecting device of the present invention has the following features:
a mounting part that is attached to a member that supports the corrugated plate; and a pair of holding parts that hold the respective ends of the two corrugated plates that are connected to each other in the direction of wave repetition by inserting them separately; The gist lies in that it consists of a long member with.

[Effect]

According to the above configuration, the elongated member prevents the ends of the two connected corrugated plates from sagging or undulation, and the elongated members also provide the required airtightness between the connected corrugated plates.・Connected without overlapping while maintaining watertightness.

〔Example〕

FIG. 1 is an exploded perspective view showing a part of the connector. The illustrated connector 10 includes a pair of elongated members (hereinafter referred to as elongated members) 11 and 12. One elongated member 11 has a flat mounting portion 13
and a holding portion 14 integrally provided at one end in the width direction of the mounting portion 13.
It has a U-shaped cross section, with a side plate 15 extending obliquely inward from the one end and a presser plate 16 folded back. Also,
The mounting portion 13 has positioning holes 17 for fasteners such as tapping screws (this positioning hole may not be provided) at a plurality of predetermined locations, and has a folded protruding edge at the other end in the width direction. It has 18. On the other hand, the other elongated member 12 includes a flat mounting portion 19 and a holding portion 20 integrally provided at the other end of the mounting portion 19 in the width direction. It has a U-shaped cross section, with a side plate 21 extending diagonally inward from the other end and a presser plate 22 folded back. Furthermore, a folded-back projecting edge 24 is formed at one end in the width direction of the mounting portion 19 .

FIGS. 2 to 4 show a state in which corrugated plates as roofing materials are connected using such a connector 10.

As is clear from FIG. 2, one elongated member 1
The attachment portion 13 of one is attached to the attachment portion 1 of the other elongated member 12.
9, and both are attached to the purlin material 2 with fasteners 30. The fastener 30 is made of a tapping screw screwed into the purlin material 2 through the attachment parts 13 and 19. Of course, a sealing material is interposed between the cylindrical portion of the tapping screw and the mounting portion 13. Hook bolts or other fasteners other than the illustrated example may be used as the fastener 30, but when a tapping screw is used as described above, if the top is open like the illustrated example, the This has the advantage that the tightening work can be done from the top easily and without any hindrance. Further, among the two corrugated plates 1, 1 connected to each other, the end portion 1a of one of the corrugated plates 1 in the wave repetition direction is inserted into the holding portion 14 of one elongated member 11, and the presser plate portion 16
It is held in a state where it is strongly pressed against the side plate portion 15. On the other hand, the end 1a of the other corrugated plate 1 in the wave repetition direction is connected to the other elongated member 12.
It is inserted into the holding part 20 of and is held in a state where it is strongly pressed against the side plate part 21 by the presser plate part 22. Note that the ends 1a, 1a of the corrugated plates 1, 1 may be adhered to the holding parts 14, 20 using an adhesive.

When the corrugated plates 1, 1 are connected in this way, the ends 1a, 1a of the corrugated plates 1, 1 are firmly held by the holding parts 14, 20 over the entire length between the purlins 2, 2. Therefore, generation of undulations at the ends 1a, 1a is prevented. Furthermore, the connecting tool 10 has a double structure in which the mounting parts 13 and 19 of the elongated members 11 and 12 in a pair are overlapped, and the side plate parts 15 and 21 of the holding parts 14 and 20 are Since it acts as a reinforcing rib and makes the mounting parts 13 and 19 difficult to bend, it can be used not only when the connector 10 is made of a highly rigid bent stainless steel product or a pultruded aluminum product, but also a synthetic resin molded product. Even in the case where the material is made with For this reason, even if the mutual distance A between the purlins 2, 2 is increased compared to the conventional case, the connection points between the corrugated plates 1, 1 will not open, and the necessary airtightness and watertightness will be ensured over a long period of time.
Therefore, it is possible to reduce the number of purlins 2 and maximize the lighting performance of the corrugated board 1.

In addition, since there is no overlap between the corrugated plates 1 and 1 at the connection point, dark stains do not occur as in the conventional case, good lighting is ensured by the corrugated plate 1, and the connection point remains clean forever. kept,
The beauty is not compromised.

Furthermore, as shown in FIG. 4, a gap B is formed between the ends 1a, 1a of the corrugated plates 1 at the connection point, so the gap B is larger than the width of the corrugated plate 1 at the construction point. The corrugated plate 1 can be saved by the size of , which improves the material yield and leads to cost reduction. Moreover, since the gap B is set to a constant size by the connecting tool 10, individual differences among workers are less likely to appear in the state after construction, making it easier to standardize construction. The rainwater that has entered the gap B is drained through the groove formed by the connector 10.

In addition, according to the connector described in FIG. The attachment portion 13 of one elongated member 11 is fitted between the edge 24 and
This has the advantage that alignment in the width direction can be easily performed.
Further, a pair of elongated members 11 and 12 are separated and the corrugated plates 1 and 1 are attached to the respective holding parts 14 and 20, respectively.
Since the ends 1a, 1a of 1 can be inserted, the holding part 1
There is also an advantage that the ends 1a, 1a can be held by the ends 4, 20 with good workability.

In the above embodiment, the connecting tool 10 was described in which the attachment portion 13 of one elongated member 11 can be overlapped with the attachment portion 19 of the other elongated member 12 at any position in the longitudinal direction without sliding. In this respect, for example, as shown in FIG. It is also possible to have a structure in which both the attachment parts 13 and 19 are overlapped by sliding and fitting into the elongated member 12. This has the advantage that both elongated members 11 and 12 can be handled in a combined state.

5 to 7 illustrate connection tools 10 with various holding portion shapes.

In the connector 10 shown in FIG. 5, the holding portion 14 of one elongated member 11 has a presser plate portion 16 that swells at its base. For example, the end portion 1a of the corrugated plate 1 in which the bulging portion 1b is formed in the holding portion 14
When inserted, the presser plate portion 16 presses against the bulged portion 1.
b to prevent it from coming off. Therefore,
The holding portion 14 holds the end 1a more reliably. The holding portion 20 of the other elongated member 12 has a similar configuration and exhibits a similar effect.

In the connector 10 shown in FIG. 6, the upper end of the holding portion 14 of one elongated member 11 is bent diagonally inward. This also causes the holding portion 14 to engage with the bent portion 1c inserted into the holding portion 14, thereby reliably preventing the bending portion 1c from coming off. The other elongated member 1
The second holding portion 20 also has a similar configuration and exhibits a similar effect.

In the connector 10 shown in FIG. 7, the holding portion 14 of one elongated member 11 has a J-shaped presser plate portion 16 extending diagonally outward from the upper end portion of the side plate portion 15. When the folded portion 1d formed on the end portion 1a of the corrugated plate 1 is inserted into the holding portion 14, the folded portion 1d engages with the presser plate portion 16, and the folded portion 1d is reliably prevented from coming off. The holding portion 20 of the other elongated member 12 has a similar configuration and exhibits a similar effect.

Note that matters other than those described above in FIGS. 5 to 7 are the same as those described in FIGS. 1 to 4. Therefore, the same parts are given the same reference numerals and detailed explanations are omitted. Moreover, although the above is an example in which a corrugated board is used as a roofing material, the same effect can be achieved when a corrugated board is used as an exterior wall material.

[Effect of idea]

As is clear from the above description, when corrugated plates are connected using the connector of the present invention, the ends of the corrugated plates are prevented from undulating at the connection point. Therefore, when using corrugated boards as roofing materials, even if the distance between the purlins is increased compared to the conventional case, the connection points of the corrugated boards will not open, and the airtightness and watertightness required at the connection points will not be maintained for a long time. Not only can the number of purlins be reduced to maximize the lighting provided by the corrugated boards.

Furthermore, since there is no overlap between the corrugated plates at the connection point, dark stains do not occur as in the conventional case, and the connection point remains clean and good lighting is maintained.

Furthermore, since a gap is formed between the ends of the corrugated plate, and this gap B is determined to a constant dimension by the connector 10, the material yield of the corrugated plate is improved by the dimension of the gap, and the cost is reduced. At the same time, individual differences among workers are less likely to appear in the state after construction, making it easier to standardize construction.

In this way, although the connecting device of the present invention has a simple structure in which the holding part and the mounting part are integrated into a long member, it can completely eliminate the problems that have been pointed out in the past, and is practical. The effect is extremely large.
